Additive composition for increasing content of bile acid in colon of piglet

The invention provides an additive composition for increasing the bile acid content of colon of piglets, which is prepared from three raw materials, namely plant essential oil, saccharomyces cerevisiae and isomaltooligosacharide in a weight ratio of 1: 3: 10. The main active ingredients of the plant essential oil are cinnamyl aldehyde and thymol, the cinnamyl aldehyde is larger than or equal to 4.5 wt.%, and the thymol is larger than or equal to 13.5 wt.%. Each gram of the saccharomyces cerevisiae contains 20 billion viable bacteria units. The plant essential oil, the saccharomyces cerevisiae and the isomaltooligosacharide of existing additive products are reasonably matched, functional damage generated in weaning stress of the piglets is comprehensively and efficiently prevented and solved, the growth performance of the piglets is improved, and the content of chyme bile acid in colon is increased. 本申请提供一种提高仔猪结肠胆汁酸含量的添加剂组合物，所述组合物由植物精油、酿酒酵母、低聚异麦芽糖三种原料构成，其重量配比为1:3:10。所述植物精油的主要活性成分为肉桂醛和百里香酚，其中肉桂醛≥4.5wt.%，百里香酚≥13
